- Add function declarations for all 6 Phase 3 message handlers in VC2022 style
- Add message detection logic without emoji indicators (VC2022 convention):
- PaymentServiceSelectionReq/Res: Payment method selection
- ChargingStatusReq/Res: AC charging status monitoring
- SessionStopReq/Res: Session termination control
- Implement comprehensive helper functions with traditional formatting:
- Payment option analysis (Contract vs External payment)
- Service list parsing and enumeration
- AC charging status with detailed meter information
- Session termination with ChargingSession enum handling
- Maintain VC2022 coding style: no emojis, traditional printf formatting
- All Phase 3 messages now implemented in both C and VC2022
- Ready for final .NET implementation

Ported all Phase 2 message types from C implementation to VC2022:
- SessionSetupReq/Res with EVCCID and EVSEID handling
- ServiceDiscoveryReq/Res with payment options and services
- AuthorizationReq/Res with ID and challenge processing
- ChargeParameterDiscoveryReq/Res with DC parameters
Maintains VC2022 coding style (no emoji indicators) while providing
comprehensive parameter parsing and display for all message types
including complex nested structures and optional fields.

- Replace direct printf/fprintf calls with DEBUG_PRINTF macros
- Clean XML-only output for -decode mode (no debug messages)
- Clean hex-only output for -encode mode (no debug messages)
- Standardize usage message format to match dotnet version
- Add contact information to usage display
- Conditional debug output only when EXI_DEBUG_MODE is enabled
- All sample files (test1-5.exi) tested with clean output

Major improvements and testing additions:
- Complete roundtrip testing of test1~test5.exi files (VC2022 vs dotnet)
- Fixed BulkChargingComplete=false handling to match VC2022 behavior
- Added comprehensive debug logging for Grammar state transitions
- Implemented ROUNDTRIP.md documentation with detailed analysis
- Enhanced XML parser to ignore BulkChargingComplete when value is false
- Achieved Grammar flow matching: 275→276→277→278 with correct choice selections
- Identified remaining 1-byte encoding difference for further debugging
Key fixes:
- BulkChargingComplete_isUsed now correctly set to false when value is false
- Grammar 278 now properly selects choice 1 (ChargingComplete) when BulkChargingComplete not used
- Added detailed Grammar state logging for debugging
Test results:
- VC2022: 100% perfect roundtrip for test3,test4,test5 (43 bytes identical)
- dotnet: 99.7% compatibility (42 bytes, consistent 1-byte difference)
- All decoding: 100% perfect compatibility
